Bottleneck adjacent matching heuristics for scheduling a re-entrant flow shop with dominant machine problem
The re-entrant flow shop environment has become prominent in the
manufacturing industries and has recently attracted researchers attention. Typical
examples of re-entrant flow shops are the printed circuit board manufacturing and
furniture painting processes where components or processed parts enter some specific
machines more than once. Similar with other manufacturing environment, identifying
appropriate scheduling methodologies to ensure high output rate is very much desirable.
The problem explored and investigated in this research is a special type of scheduling
problem found in a re-entrant flow shop where two of its processes have high tendency of
exhibiting bottleneck characteristics. The scheduling problem resembles a four machine
permutation re-entrant flow shop with the routing of M1,M2,M3,M4,M3,M4 where Ml
and M4 have high tendency of being the dominant machines. The main objective of this
research is to take advantage of the bottleneck characteristics at the re-entrant flow shop
and use it to develop heuristics that can be used to solve its scheduling problems. There
are four major concentrations in this research. First, basic mathematical properties or
conditions that explain the behaviour of the bottleneck processes were developed to give
an insight and clearer understanding of the re-entrant flow shop with dominant machines.
Second, four new and effective scheduling procedures which were called BAM1
(Bottleneck Adjacent Matching 1), BAM2, BAM3 and BAM4 heuristics were developed.
Third, bottleneck approach was utilised in the study and the analysis using Visual Basic
macro programming indicated that this method produced good results. Fourth, the
Bottleneck Scheduling Performance (BSP) indexes introduced in the BAM heuristics
procedure could be used to ascertain that some specific generated job arrangements are
the optimum schedule. As a general conclusion, this research has achieved the objectives
to develop bottleneck-based makespan algorithms and heuristics applicable for re-entrant
flow shop environment. The experimental results demonstrated that the BAM heuristics
generated good performances within specific P1 (first process) bottleneck dominance
level and when the number of jobs increases. Within the medium to large-sized problems,
BAM2 is the best at weak PI dominance level whereas BAM4 is the best at strong P1
dominance level

ARENA simulation training guideline for assembly line
As a beginner for the unfamiliar software such as Arena Simulation, it is
very tough when we need to do a simple model by referring to the textbooks or journal
articles that contains a lot of difficult words to understand. Therefore, a guideline was
created to solve this problem that contains simple wordings, more infographic and the
simple step by step procedures that are easy to follow, understand and to help the
users. The purpose of the study was to build a training guideline for modeling an
assembly line by using Arena Simulation, to build a model representing the assembly
process using the training guide, and analyze the simulation result for the assembly
line model. The study was conducted using Arena Simulation software. The data was
collected based on the actual model to be inserted into the system setting for
validation purposes. The model was created with 32 hours replications length to
achieve accuracy in the result. The difference between the actual and simulation
model must be below 5% percent to said the model is valid. To verify the guideline
is applicable we build another example of the model and compared the simulation
result with the actual simulation data from the textbook. To validate the model, we
calculated the percentage difference between the actual and simulation model results.
This simulation finding indicated that the guideline is suitable to be used as a learning
tool and reference for users to model an assembly line. To conclude, this project has
successfully provide a basic guideline for modelling an assembly line using Arena
software and there is still a lot of rooms for future improvement
Sustainable development: A Malaysian perspective
Sustainable development is all the rage. Malaysian firms too have been quick to jump into the bandwagon, especially with regards to their corporate social responsibility (CSR) initiatives. However, sustainable development has been increasingly interpreted from a strictly Western-centric value system.This may pose challenges to Malaysian firms as they adopt sustainable practices into their operations.Four key issues are presented and discussed, particularly in relation to Malaysian’s socioeconomic landscape.Following that, this paper calls for a return to the fundamentals of sustainable development, which is unfettered to value suppositions and instead focused on more pragmatic reasons.To that end, this paper proceeds to make
recommendations of a more suitable approach in embracing sustainable development in Malaysia that would bring about a virtuous cycle of enrichment for the business sector as well as the society

Microclimatic Conditions of an Urban Square: Role of Built Environment and Geometry
AbstractGeometry plays a dominant role in thermal situations within city structures. This study aims to seek how this role affects thermal comfort of the visitors in an urban square. Computer simulations were performed along with physical measurements in an urban square during peak hot conditions of summer in Isfahan, Iran. In addition to the influence of built environment inside the square, the results confirmed the role of geometry on thermal conditions. The amelioration effect for the aspect ratio was higher than that of the orientation. Findings are useful for urban design strategies dealing with thermal comfort
Impacts of Courtyard Geometrical Configurations on Energy Performance of Buildings
The courtyard is an architectural design element often regarded as microclimate modifiers. It has the potential of improving comfort conditions within the outdoor courtyard space and the enclosing indoor spaces. Harnessing the optimum benefits of courtyards depends on several conditions namely the orientation and configurations of the courtyards, as well as the treatment of the external surfaces of the enclosing building envelopes. As three variables of orientation, number of floors and wall envelope have not been investigated in a single study, therefore, this parametric study was performed to investigate the microclimatic influence of varying courtyard geometric configurations and its enclosing facades in hot and humid climate using IES<VE> simulation tools. The study observed the environmental impact regarding thermal performance and energy consumption of the enclosing indoor spaces. The results suggest optimum conditions to harness the potential of courtyards to lower energy consumption of buildings in the tropics.Keywords: courtyard; thermal performance; energy consumption; simulationeISSN: 2398-4287 © 2019.
